Does he know that knotting could impregnate him? He’s playing a dangerous game if he already knew. ♀

Its because he never learn about omega stuff since he never had heats or any other normal omega effects, all this is new to him since the doctors and everyone thought his heat will never come so there was no reason for them to explain all that to him. Remember that he was introduced as "half-omega" in the begging?
I feel bad siwoo had to grow up so early. Also I’m so happy because I think he’s about to propose but I don’t want this to end.
